posted October 30, 2003 5:46 PM I'm retrieving a binary file from an FTP site and it seems to grow when it's downloaded. Here's my C# code: ftp = new Dart.PowerTCP.Ftp.Ftp(); ftp.ServerPort = 21; ftp.Server = txtServer.Text; ftp.Username = txtUsername.Text; ftp.Password = txtPassword.Text; ftp.DoEvents = false; ftp.Passive = false; ftp.Restart = false; ftp.Timeout = 30000; //30 second timeout Dart.PowerTCP.Ftp.Listing myList = ftp.List(txtRemotePath.Text + txtFileName.Text, true); Dart.PowerTCP.Ftp.ListEntry le; if (myList.Count == 1) { le = myList[0]; filesize = le.Size; } DartFiles = ftp.Get(txtRemotePath.Text, txtFileName.Text, txtLocalPath.Text, false); Later in the code I compare the filesize var to the file size of the actually file downloaded. The original file size was 14176 and the downloaded filesize is 14219. Is there a setting for the component that I need to set? This is a binary encrypted file. Thanks mark |

posted October 30, 2003 5:48 PM typo... the original filesize on the FTP server was 14176 but it's size on my local hard drive after downloading was 14219. TIA |

posted October 30, 2003 5:52 PM Ok, I added this property to the mix and it seemed to work: ftp.FileType = Dart.PowerTCP.Ftp.FileType.Image; Does Image mean binary? This certainly isn't an FTP standard is it? And can I change the FileType prior to each retrieval so that I can retrieve binary files and text files during the same session?? thanks |

posted October 30, 2003 11:28 PM The second yes needs more explanation. When you set binary mode on an FTP server the command is "MODE I" where the "I" is for image. That's why we chose that name for the constant. |
